If you were roller-skating you don't need friction because it slows you down.
Well you want friction between the wheels and the floor (so you do not slip sideways) but not between the wheel and the axel (thats why you have ball bearings there to reduce rolling friction).
If you are ice skating you do not want friction between the blade of your skates and the ice.
What else can I help you with?
Do you need friction to shine a flashlight?
No, you do not need friction to shine a flashlight. A flashlight works by converting electrical energy into light through the use of a bulb or LED and battery. The light produced does not rely on friction to be emitted.
Why do f1 cars need friction?
F1 cars need friction to maintain grip on the track and maximize traction, allowing for better acceleration, cornering, and braking performance. Friction is essential for the tires to generate the necessary grip to navigate the high-speed corners and stop effectively during racing conditions.
Draw squares around the places where there should be low friction (samir)?
Low friction would be desired on surfaces where objects need to slide easily, such as drawer tracks, door hinges, and rollerblade wheels. These areas would benefit from reduced resistance to movement, making it easier to navigate and operate smoothly.
Do pencils need friction to write with?
Yes, pencils need friction in order to write. The friction between the pencil lead and the surface of the paper allows the lead to leave a mark as it rubs off onto the paper. Without friction, the pencil lead would not be able to transfer onto the paper.
Why do you need friction?
Friction is needed to create traction, which allows us to walk, grip objects, and drive vehicles. It also helps to stop moving objects and convert kinetic energy into thermal energy. Without friction, objects would slide uncontrollably, making movement and handling difficult.
What places don't you need friction on a sleigh?
Between the runners and the snow.
What type of surface increseed the friction?
rough places
Do you need friction for lacrosse?
yes! you need friction for lacrosse so you don't fall
Where should there be low friction when riding a mountain bike?
i think you need the most friction in your feet and handsIt's hard to say where you'd need the mostfriction, as riding a bike requires several thingsto work together. And in each of those places you need enough friction.-you can't ride if tires will slip too badly on the ride surface-you can't ride if tires will slip too badly on the rims-you can't ride if wheels won't stay in the frame/fork-you can't ride if you can't stay on the bike
Jill is climbing where does she need high friction?
On her feet and hands. That is why they build climbing shoes from sticky rubber. Her belay partner will need friction in their belay device (ATC OR GRI GRI, etc)
Do seesaw need more friction or less friction?
than what?
Does friction help ships?
In some places it is essential. Others it is detrimental.
How do friction affect?
We would need to know what the friction is to affect to respond to this question.
What does heat need to exist?
friction
Does a car need friction?
Yes
Do you need friction for typing on a keyboard . why?
Because without friction, it would not be successful when typing!
Sliding kinetic friction or rolling kinetic friction?
